Is AI iMessage Auto-Reply Safe?

The main risk is the automatic send

An AI draft gives you a chance to catch a bad answer. An AI auto-reply removes that review step. GhostReply can send a message that sounds plausible but is wrong, too confident, mistimed, or inappropriate for the relationship. It may infer a schedule, name, promise, or emotional meaning that was never stated.

That does not make every use unsafe. A low-stakes acknowledgment to a trusted friend may have a small downside. A response about money, health, an emergency, consent, a contract, a client deadline, or a confidential matter can have a large downside. Judge safety by the cost of the worst plausible reply, not by how good the average reply looks.

Where your iMessage data goes

1. GhostReply reads the Messages database locally on your Mac after you grant Full Disk Access to the terminal app.
2. It stores configuration, a reply profile, and local usage statistics under ~/.ghostreply.
3. For profile and reply generation, selected conversation samples and relevant context go directly from your Mac to Groq using your API key.
4. Message content does not pass through GhostReply's servers. Trial accounting, license validation, and analytics data can reach GhostReply services.

This means GhostReply is not a fully local AI system. History access and stored profile data are local, while inference is a cloud request to Groq. You should have the right to process the conversation content you send and consider whether the other person's expectations, your contracts, or applicable rules permit that processing.

Groq's current data documentation says usage metadata is retained and inference customer data is not retained by default, but it also describes limited temporary logging for reliability or abuse monitoring and optional account controls. Policies and settings can change. Review the current document and your Groq data controls instead of assuming zero retention. Also read the GhostReply privacy page.

Permissions are powerful by design

GhostReply needs a Mac signed in to Messages, Terminal or another supported terminal app, an internet connection, and your Groq key. Full Disk Access lets the terminal read the local Messages database. Messages Automation permission lets that terminal control Messages and send. Contacts access helps display names instead of raw handles.

Only grant these permissions to a terminal and software source you trust. It auto-sends only while the Mac is awake and GhostReply is running. Closing the app stops the session. Revoke Full Disk Access or Automation in macOS System Settings if you no longer want the software to have that capability.

Controls GhostReply provides

• Scope: Choose one person or all incoming one-to-one chats. Group chats are skipped.
• Visible session: GhostReply runs in Terminal and prints the incoming text and sent reply.
• Manual takeover: After GhostReply has answered a contact, your reply stops one-person mode or pauses that contact for 30 minutes in all-contacts mode.
• Urgent heuristic: Keyword matches are skipped and surfaced as a notification.
• Sensitive heuristic: Keyword matches can receive a generic holding reply and a notification.
• Off switch: Stop or close the running app to end automatic replies.

These controls reduce risk, but none guarantees accuracy, correct classification, delivery, or appropriate tone. Generated safeguards are not a substitute for direct monitoring.

Safe-use checklist

• Start with one trusted contact, not everyone.
• Use the 10 free replies while you can watch the session and verify the actual outputs.
• Tell the contact when AI assistance would be material to their expectations or consent.
• Avoid children, vulnerable people, strangers, disputes, sensitive personal data, and high-stakes topics.
• Do not treat urgent or sensitive heuristics as guaranteed detection.
• Stop GhostReply before a conversation becomes consequential or emotionally complex.
• Review your local profile and configuration, Groq controls, and granted macOS permissions periodically.
